Singtel partners Palo Alto Networks to launch quantum-threat protected network

Its hybrid quantum-safe network combines hardware and software methods to protect data against quantum-computing threats

[SINGAPORE] Singtel on Thursday (Oct 23) announced the launch of the first hybrid quantum-safe network in South-east Asia, partnering cybersecurity company Palo Alto Networks.

Its hybrid quantum-safe network (QSN) combines hardware and software methods to protect data against quantum-computing threats.

Quantum computers can break traditional encryption methods at an “alarming speed”, according to an article by accounting firm KPMG, rendering ineffective encryption tools used to protect banking transactions, business data and more.

“Quantum computing represents one of the greatest opportunities of this decade… but it also presents one of its biggest risks,” said Singtel chief executive Ng Tian Chong. “Our hybrid QSN gives enterprises a practical and scalable way to protect their most sensitive data.”

Singtel’s new network combines quantum key distribution, which securely transmits encryption keys, and post-quantum cryptography, a new generation of algorithms “engineered to resist quantum attacks”.

Its protection can thus extend beyond data centres and mission-critical sites to branch offices, remote facilities, cloud environments and overseas operations, said Singtel. Fibre-based quantum key distribution has limitations around distance, it added, which the hybrid QSN overcomes.

It also leverages Palo Alto Networks’ post-quantum cryptography software-based feature that adds quantum-safe encryption to existing infrastructure, as well as ID Quantique’s quantum key distribution platform.

Singtel signed a memorandum of understanding with Palo Alto Networks to extend its QSN through the cybersecurity company’s post-quantum cryptography solution. The partnership will allow Singtel to offer hybrid QSN as a “managed security service” for businesses.

Its hybrid nature means that quantum key distribution can be used to protect hospitals and data centres, while post-quantum cryptography can extend protection to polyclinics. The same could apply to bank headquarters and smaller branches, or power grids and substations, respectively, said Singtel.
